Why is hunger and thirst for righteousness important for Christians?

Hunger and thirst for righteousness is essential for Christians as it indicates a sign of spiritual life and awareness of our need for Christ. Jesus highlights this in His teaching; those who are aware of their spiritual condition—poor in spirit and mourning over their sin—will actively seek the righteousness that comes from God. The hunger and thirst signify our need for Jesus, who is our righteousness, and point to our ultimate fulfillment found in Him alone. Without this longing, one may not recognize their need for salvation and the sufficiency of Christ's atoning work.
